ISO 26433:2009定义并描述了使用XML作为数据描述语言的应用程序的D-cinema元数据结构中使用的常见数据类型。ISO 26433:2009还包括在其他地方定义的类型和标识符的规范性参考，这些在标准文档中使用XML时是必要的。ISO 26433:2009中定义的类型的结构和组成旨在足够简单和通用，以促进在其他标准中的可重用性。

ISO 26433:2009 defines and describes common data types used in D-cinema metadata structures for applications using XML as a data description language. ISO 26433:2009 also includes normative references for types and identifiers defined elsewhere that are necessary when using XML in standards documents. The structure and composition of the types defined in ISO 26433:2009 are intended to be sufficiently simple and general to promote reusability in other standards.
